<br clear="all">Hi all,<br>I am Vinod. I am trying to install IPOPT on my windows machine using cygwin. I have third party components BLAS, LAPACK and HSL in home/vinod/ipoptdir/coinipopt/thirdparty/Blas Lapack and HSL respectively (as per the documentation). But when I am trying to configure ipopt by the command "./configure" it is showing the following error.<br>
<br>"checking whether lblas has BLAS -no<br>configure: error: cannot find
BLAS<br>
./configure failed for ipopt"<br><br>If anybody know about this please reply me. <br><br>Thank you all.<br>-- <br>Vinod Siram<br>M.Tech, IIT Bombay<br><br>
